TURN-BUTTON FASTENER.

Specification of Letters Patent.

Application filed October 5, 1918. Serial No. 257,049.

support such as the body of a vehicle or a, member of the frame of a-vehicle top, and

formed to enter a buttonhole or eyelet in a curtain or cover portion, and an oblong but-- ton pivoted to the shank and formed to register with and freely enter a' buttonhole when turned to one position, and to be turned crosswise of the buttonhole to overhan portions ofthe margin thereof and co e the curtain or cover portion against removal from the shank. The shank is usually of oblon form corresponding to that of the buttonho e and button.

In Letters Patent No. 1,253,350, dated January 15, 1918, I show a type of turn button fastener in which the shank and its attaching base are made in a single sheet metal piece or part, and are adapted to cooperate in yieldingly confining the button in either of the described POSltlOIlS, without the employment of retainingdevices supplemental to the shank and formed separately therefrom.

The present invention consists in certain improvements on the said patented fastener which I will now proceed to describe and claim.

The invention has for its'chief object to enable the button to be yieldingly confined a turn-button fastenerembodying the invention, said parts being separated.

F 2 .shows in section the parts shown by Fig. 1 when assembled.

Fig. 3 is a section on the plane of line 3'3, 1Fig. 2, "and a plan view of parts below said Fig. 4 is a view similar to Fig. 3, showing a different adjustment.

Figs. 5 and' 6 are fragmentary sectional views illustrating a different construction of the button stud hereinafter described.

' Fig. 7 is a fragmentary perspective view illustrating the stud shown by Fig. 5.

Fig. 8 is a view similar to Fig. 6, showing a different arrangement of the bearing flanges'hereinafter described and a spring washer.

Fig. 9 is a view similar to Fig. 8, the washer being omitted.

The same reference characters indicate the same parts in all of the figures.

In the drawings, '16 represents the shank and 17 the button of a turn-button fastener. The shank is a hollow post, formed from sheet metal by suitable dies and of oblong form in cross section, the shank being provided at its inner end with an attaching base 18, adapted to be secured to a support.

The head of the shank is divided by slots 19 into sections, said slots being preferably extended through the upstanding wall of the shank, as indicated at 19, Fig. 1. The head therefore includes 'two separable sections, which are yieldingly pressed together by the resilience of the base 18, which continuously surrounds the shank.

The meetingedges of the head sections are provided with coinciding recesses 20, forming an expansible angular hearing, which is extended or widened by flanges 20 integral withthe head sections.

The button 17 is provided with an angular stud 21, journaled in said bearing, the form of the bearing and stud being such that, when the stud is turned, it alternately expands the bearing, as indicated by Fig. 4, and permits the bearing to close, as shown by Fig. 3. When the bearing is closed, it is adapted to yieldingly confine the stud and button in different angular positions.

As here shown,the bearing and stud are of polygonal form, the stud being preferably rectangular, with slightly rounded corners, and the bearing being preferably provided with faces 20*, which are obliquely arranged to prevent the corners of the shank from binding inoperatively when the shank is turned from the position shown by Fig; 3 to that shown by Fig. 4:.

The structure thus far described is substantially the same as that disclosed by the above-mentioned patent. In accordance with the present invention, I provide the means next described for confining the stud 21 against endwise movement in the bearing and withdrawal therefrom. As shown by Figs. 1 and 2, the button and shank are hollow, and formed from sheet metal, the shank being provided with a reduced extension 21 of lesser thicknessthan the body of the stud and adapted to be upset, as shown by Fig. 2, and thus form a bur on the inner endof'the stud. A washer 23 is applied to the extension 21% before the latter is upset, said washer being engaged with the bur, and constituting a wear-sustaining stud-enlargement and contacting with the portions of the stud head formed by the inner ends of the flanges 20 As shown by Figs. 5, 6 and 7, the stud and button may be solid, the inner end of the stud being preferably cylindrical and provided with a recess 24, the margin of which is adapted to be upset to form a bur 24*, as shown by Fig. 6. A washer 27 is applied to the stud before its outer end is upset, as indicated by dotted lines in Fig. 5, and secured by the bur, as shown by Fig. 6.

When the button and its shank are constructed of sheet metal, they may be made from a sheet metal blank having a seamless central portion forming the bottom of the button and the shank 21, and wings forming thesides and top of the button, said wings meeting to form a joint or seam 145, as shown by Figs. 1 and 2. 1

The bearing flanges may project upwardly from the sections of the shank head, as shown by Figs. 8 and 9, where said flanges are designated 20, the bottom of the button having a recess 30 receiving the flanges. The flanges 2Qprojecting outwardly maybe more conveniently formed integral with the stud head than the inwardly projecting flanges 20; 'Moreover, when the said flanges project outwardly, the inner sidesof the head sections present fiat faces forming extended bearings for the shank enlargement, whether said enlargement be the washer 27, or the bur 24; shown by Fig.9, thewasher being omitted. The washer may be'curved and resilient, as shown by Fig. 8, to exert a downward yielding pressure'on the shank and button, preventing the button from rattling.

The washer 27 constitutes a wear-sustainingstud-enlargement"confining the stud in the bearing and'ha-ving a diameter greater than "that-of the bur, the diameter of the washer being sufficient to compensate for the separation of the head sections from each other by the stud when the latter is turned to the position shown by Fig. i, so that the operative bearing of the stud-enlargement on the head sections is not affected by the'eX- pansion of the head. bur 24:? is necessarily limited. Moreover, said bur, especially in the sheet metal form shown by Figs. 1 and2, is liable to be cracked at intervals when it is being formed, so that it is not continuous. This is an objection which I overcome by the employment of a wearsustaining washer'supplementing the burl I claim:

1. A turn-button fastener comprisingv a shank having an attaching base, a head divided into separable sections which are yieldingly pressed toward each other, the opposed.

edges of said sections having coinciding recesses forming an expansible bearing, a button having a stud journaled in said bearing, and yield-ingly confined thereby in different angular positions, the inner end ofthe stud being upset to form a bur, and a washer engaged with said bur and constituting a continuous annular wear-sustaining -stud-enlargement confining the stud in the bearing, said washer having a diameter greater than that of the bur, and sufiicient to'compensate for the separation of the head sections from each other by the stud; i

2. A turn-button fastener comprising a shank having an attaching base a head divided into separable sections which are yield.- ingly presseditoward each other, the opposed edges of said sections having" coinciding rejcesses forming an expansible bearing, .a"'blltton having a stud journaled in saidibearing, and yieldin-g'ly confined thereby indifferent angular positions, theinner end of the stud being upset to form a bur, and fa Washer 11- gaged with said bur and constituting a Wearsustaining studeenlargement bearing on, portions of said head and confining the stud in the bearing, said washer being curved and resilient to prevent rattle of the button. 7 i 3. A turn-button fastener comprising a shank having an attaching base, a head-cit vided into separable sections which are yieldingly pressed toward each other, the opposed edges of said-sections having coinciding re cesses, and: outwardly projecting flanges coinciding with said recesses and forming an expansible bearing located atone the head, the inner sides of the {head sections forming flat faces below the bearing,abutton having astud journaled in said bearing and yieldingly confined thereby in difierent angular positions, the inner end of the button ibeing recessed to receive said flanges,-and the inner end of the stud being upset to form a'bur, and a washer engaged with said buriand Gonstituting a wear-sustaining stud enlargement stud in the bearing.

The diameter of the 4. A turn-button fastener comprising a shank having an attaching base, a head divided into separable sections which are yieldinglypressed toward each other, the opposed edges of said sections having coinciding recesses, and outwardly projecting flanges coinciding with said recesses and forming an expansible bearing located above the head, the inner sides of the head sections forming flat faces below the bearing, a button having a stud journaled in said bearing and yieldingly confined thereby in difl'erent angular positions, the inner end of the button being recessed to receive said flanges, and the inner end of the stud being upset to form a bur,

and a washer engaged with said bur and constituting a Wear-sustaining stud enlargement bearing on said flat faces and confining the stud in the bearing, said washer being curved and resilient to prevent rattle of the button.

Copies of this patent may be obtained for five cents 5.
